Aplication led March 25, 1921. Serial No. 455,508.

This invention relates to machines for op-A erating on soles and more particularly for providing the margin of a sole, such as an insole, with an edge adapted to permit attachment thereto of an upper.

One of the objects of this invention is to provide a machine in which the operations on the sole by the tool and the feed thereof by the feeding instrumentalities are so accomplished as to obviate marring of the sole.

Another object of this invention is to proa vide a machine which, while operating to the nished sole.

v laterally cut from the margin of the sole a strip and provide an overhanging shoulder to which the upper can be attached, is so constructed as to feed the sole by engagement therewith at the margin and that portion which is subsequently cut off so as to prevent marring of Further objects will appear from the detail descriptiontaken in connection with the accompanying drawing, in which:

Flgure 1 is a detail front elevation of a machine embodying this invention;

Figure 2 is a detail side elevation;

Figure 3 is a detail rear elevationg Figure 4 is a detail sect-ion on the line 4 4, Figure 3;

Figure 5 is an enlarged section showing the operation of the tool;

Figure 6 is a detail perspective view showing1 the different parts of the mechanism; an

Figure 7 is a detail showing the sole.

Referring to the accompanying drawing, and more particularly to Figure 7, the insole l, as shown, has a wing 2 thereon with an overhanging shoulder 3 arranged above but inside of the wing. This sole is formed by slitting thesole edge thereal'ong on the line 4C, thereby forming a lip 5, and by severing the lip by a cut taken along but inside of the sole margin but at an acute angle so as to form the overhanging shoulder 3.

Referring to Figure 5 and 6, the slit 4 is formed by a slitting knife 6 which bevels and from front to rear as shown, while the sole face laterally extending point which intersects the point of the slitting knife; thecutting edge of the slitting knife is, however, arranged in advance of the cutting edge of the rearwardly with the carrier angular shoulder 3.is formed by a' cutter 7 having a downwardly and sole face cutter 7 so that the slit willbe completely formedbefore the cut extending'into the slit is taken; accordingly, these two cut-- ters combine to sever from the sole edge, the strip .5.

In the villustrated embodiment of this invention, the slitting knife and cutter are mounted on a carrier which in turn is mounted for movement forwardly and backwardly over a work support, on which the sole is mounted with its inside face arranged uppermost. Cooperating with the sole is a presser-gage which holds the sole down on the table, a sole edge gage which positions the sole laterally, and a presser-foot or work retainer which is adapted to engage the sole and which is arranged for vertical movement with the sole so as to clamp the same on the work support and then release the same. While the sole is clampedv by the presser-foot the slitting knife and cutter move forwardly with their carrier and the presser-gage attached thereto so as to take a short cut; after the knife and cutter come to rest, the presser-foot is raised to release the work and then the knife andcutter; move thereby feeding then again enoperations arc the work; the presser-foot gages the work and the repeated.

Referringnow to Figures 1 to 6 inclusive, 10 designates a machine head which has mounted thereon a carrier 11 which is arranged for movement back and forth. The

`frame has mounted therein a presser-foot 12 which is mounted for vertical movement so as to engage and disengage the sole whichl is mounted on a suitable work table 13. A suitable edge-gage 14 is provided which is arranged for lateral Vadjustment to provide for various extensions. A presser-gage 15 is mounted on the carrier l1 and is arranged to extend down to the upper face ofthe sole. The slitting knife 6 is clamped on a shank 16 by screws 160 which shank, in turn, is adjustably mounted on the carrier l1, being adjusted by ascrew 17. The parts so far described may, 1n a general way, be of the construction as shown in the United States Patent No. 1,023,801, dated'April 23, 1912. As in the machine of the patent, the carrier l1 is moved back and forth in timed relation with the 'movement of the presser-foot 12 by suitable mechanism operated from the power shaft, but not shown.

The slitting knife 6 is mounted on' the movable carrier 11, and also mounted on this carrier and clamped to a lug 18 thereon (on the opposite sideof Which is also clamped the presser-gage l5) is a bracket 19 on which is adjustably mounted the cutter 7, the adjustable mounting being through a screw 2O engaging a slot in the cutter and threaded into the bracket 19. The presser-gage 1.3 has a foot 21 Which extends over the margin of the sole supported on the table and slightly beyond the tip of the slitting knife. The presser-foot l2 has a foot 22 which extends over the margin of the sole and inwardly for some distance beyond the presserfoot 2l and the knife and cutter', and this presser-foot has a roughened portion 23 arranged between the tips of the knife and cutter and the margin of the sole. The presser-foot further has a lug 24 arranged to extend into a slot 25 in the presser-foot when they come together.

i During the operation of the machine and assuming the presser-foot to be downto c lamp the sole on the table as the carrier 11 moves forwardly carrying the knife and cutter With it, the slitting knife will operate in advance of the cutter to slit the sole While the cutter will sever the strip. or lip 5 and form the shoulder 43; as the carrier comes to rest, the presser-foot Will be raised and thecarrier will then shift carrying the sole with it and feeding the same; the presser-foot then again comes down on the sole to y retain thevsame and the operation is repeated. It Will be noted that the roughened portion 23 of the presser-foot engages that part of portion of the sole margin which is subsequently cut off; accordingly, the inner face of the insole is not marred but left smooth. Both the slitting knife and the cutter can be adjusted by manipulation of the screws 17, 20 and 1GO, While both the knife and the cutter can be removed to permit grinding of the same.

It is obvious that various'changes may be made in the details of construction Without departing from the spirit of this invention; it is, therefore, to be understood that this invention is not to be limited to the specific details shown and described.
